BEDFORD, Mass.--(BUSINESS WIRE)-- Ocular Therapeutix ™, Inc. (NASDAQ: OCUL), a biopharmaceutical company focused on the formulation, development, and commercialization of innovative therapies for diseases and conditions of the eye, today announced financial results for the second quarter ended June 30, 2018 and provided a business update.

“We are encouraged with our progress through the first half of 2018,” said Antony Mattessich, President and Chief Executive Officer. “The on-time resubmission and establishment of a December 28th PDUFA date for DEXTENZA® were critical achievements and we are pleased to have accomplished them. Clearly, we need to demonstrate that the transformation we have experienced internally translates to externally-validated results. While the team understands the approval of DEXTENZA is our top priority, we will continue to drive our pipeline forward which should be increasingly appreciated as we demonstrate our ability to execute.”

Key Highlights and Upcoming Events

DEXTENZA® New Drug Application (NDA) resubmission completed and accepted by the U.S. Food and Drug Administration (FDA). Ocular resubmitted the NDA to the FDA on June 28th and announced the acceptance of the filing on July 19th. As expected the resubmission will be treated as a Class 2 response with a six-month review period. The target action date under the Prescription Drug User Fee Act, or PDUFA, is December 28, 2018.

Initiated commercialization planning for DEXTENZA.If DEXTENZA is approved,Ocular intends to launch it with a specialty sales team and has begun executing on the commercial build-out.

OTX-TP (travoprost insert) Phase 3 topline efficacy data for the treatment of glaucoma expected in the first half of 2019. Enrollment in the 550 patient Phase 3 trial remains steady and the Company continues to anticipate topline data in the first half of 2019. The Company has also dosed the first patient in the third quarter in an open-label, one-year safety extension study that will be included as part of the current pivotal program. This study will provide additional long-term safety data with repeat administration of OTX-TP.

Initiated OTX-TKI (tyrosine kinase inhibitor implant) ex-U.S. Phase 1 clinical trial; the first patient is expected to be dosed in the third quarter. OTX-TKI is a bioresorbable, hydrogel fiber implant with anti-angiogenic properties delivered by intravitreal injection being developed to treat patients with wet Age-related Macular Degeneration (AMD) and other retinal diseases. Preclinical data have demonstrated the ability to deliver an efficacious dose of OTX-TKI to the posterior segment of the eye for the treatment of VEGF-induced retinal leakage for an extended duration of up to twelve months. The Phase 1 trial is a multi-center, open-label, dose escalation study testing the safety, durability, and tolerability of OTX-TKI.

Regeneron collaboration continues for the development of OTX-IVT (aflibercept implant). The Company, along with Regeneron, continues the pre-clinical development of an extended-delivery formulation of the VEGF trap aflibercept (EYLEA®), delivered by intravitreal injection, for the treatment of retinal diseases such as wet AMD.The Company remains pleased with the state of the collaboration and the teams have been working well together.

Second Quarter 2018 Financial Results

As of the quarter-ended June 30, 2018, the Company had $56.8 million in cash and cash equivalents versus $62.9 million at the end of the first quarter of 2018. The cash balance benefited from $8.4 million in net proceeds generated from the sale of common stock under the Company’s 2016 Sales Agreement, or ATM, during the second quarter of 2018. Offsetting the ATM inflows during the quarter were a net loss of $13.8 million, principal debt payments of $1.6 million, and capital expenditures of $0.6 million. At the end of Q2 2018, $24.1 million remained available to be sold under the 2016 Sales Agreement and the Company will continue to monitor the opportunity to sell additional common stock as appropriate under the facility.

Based on the Company’s current plans and forecasted expenses, Ocular Therapeutix believes that existing cash and cash equivalents will fund operating expenses, debt service obligations, and capital expenditures into the second quarter of 2019, exclusive of the potential $10 million option payment from our Regeneron partnership.

Research and development expenses for the second quarter were $8.7 million versus $8.1 million for the second quarter of 2017 and reflect an increase in compensation costs associated with additional hiring primarily in the technical operations and quality departments, as well as an increase in facilities expenses associated with additional lab space at corporate headquarters.

Selling and marketing expenses for the second quarter were $0.9 million as compared to $6.8 million for the same quarter in 2017. This decrease relates to a significant reduction in pre-commercial activities as a result of the delay in the launch of DEXTENZA.

General and Administrative expenses were $4.4 million for the second quarter versus $3.7 million in the comparable quarter of 2017. The increase in expenses stemmed primarily from increases in legal costs related to the defense of ongoing legal proceedings.

Revenues for the second quarter of 2018 were driven exclusively by ReSure Sealant and totaled approximately $0.6 million compared with $0.4 million in the same period for 2017, reflecting principally an increased number of units sold.

The Company reported a net loss of $(13.8) million, or a loss of $(0.37) per share for the second quarter of 2018. This compares to a net loss of $(18.7) million, or a loss of $(0.64) per share, for the same period in 2017. The net loss for the second quarter of 2018 included $2.4 million in non-cash charges for stock-based compensation and depreciation compared to $2.1 million for the same quarter in 2017.

The Company had approximately 38.5 million shares issued and outstanding as of June 30, 2018 compared to 37.3 million shares issued and outstanding as of March 31, 2018.
